CHURN ATTACHMENT FOR WASHING MACHINES.

Application led May 28, 1926. Serial No. 112,399.

My invention relates to a churn attachment for washing machines of th etype comprising a vertical standard which drives a dash element for thewasher with a partial rotation back and forth iii the washing vessel.

The motion obtainable in Washing machines of this kind is highly suitedto the churning of milk, washin and I have conceived that machines ofthis type can be readily and easily converted to use as a churn by theremoval of the dash from the washing vessel and the substitution of acombination churn vessel and dash, the dash element preferablycorresponding to the dash of the washing machine but being integralwitlr the churn vessel so that the churn attachment can be readilysubstituted for the dash element of the washing machine and operatedwithin vessel.

More particularly,

the washing my invention contemplates the provision of a churn vesselhaving its bottom, carrying the dasher elements, surrounding a tubularstandard by means of which it is adapted to be mounted on the dashactuating shaft of the washing machine.

My invention further comprises the novel details of construction parts,which will be more fully un and arrangements of derstood by reference tothe accompanying drawings and to the description thereof in thefollowing specification and claims.

According to the drawings Fig. 1 illustrates conventionally the type ofwashing machine with which my invention is adapted for use as anattachment, the churn attachment shown in section.

Fig. 2 is an enlarged perspec churn attachment partly broken tive of theaway; and

Fig. 3 is a sectional elevation of the cover for the churn attachment.

Similar reference numerals refer to similar parts throughout thedrawings.

In the embodiment of my invention illustrated, I have shown the churnapplied as an attachment to a typical washing machine 1,

comprising a dasher standard 2 which, by the washing machine mechanismbe shown or described that need not in detail as the same forms no partof my present invention, is

given a partial rotation back and forth about its long axis. In practicethe standard 2 is generally it is provided with suitable bear adapted tofit snugly rotated through about 270, and

ings and is within a dash sleeve 3 which is closed overhead and causedto interlock with the shaft by means of a square soclret 4 engaging asquare end 5 on the shaft, or .in any other suitable way. This sleeve atits lower end is provided with a circumferential flaring flange 6 whichpresents an annular concavo-convex face that is traversed by radial finsor dasher blades 7 All of the parts thus far described are standard forthe dash of washer machines of the character in question.

To convert this dasher element into a churn, I mount about the outerperiphery of the fiange a cylindrical vessel 8 having the depth andcapacity designed for the churn, and when the washing machine dasher hasthus been converted into a churn it is mounted on the standard 2 and thelatter is driven with its partial oscillatory rotation, so that the milkwill be caused to surge back and forth about the standard and will beagitated by the vanes so that it will be rapidly ehurned in an efficientand effective manner. After the churning operation, the churn elementcan be disengaged from the standard 2, and it is of the type which canbe readil cleaned and thereafter the standard was er dash without thevessel attachment 8' can be replaced on the standard, thus restoring themachine for washer service.

It is understood that the churn vessel is of a size which can be readilyintroduced through the top opening 9 in the washing vessel 1 withoutdisturbing the latter.

I provide a suitable lid 10 for closing the top of the churn vessel andwhich is disposed to clear the top of the sleeve 3 when mounted.

Though I have described with great particularity the details of theembodiment of the invention herein shown, it is not to be construed thatI am limited thereto, as changes in arrangement and substitution ofequivalents may be made by those skilled in the art without departingfrom the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A churn attachment for machines having a partially rotatableoscillatory vertically disposed shaft, which comprises a sleeve ada tedto be mounted for rotation with said sha t, dasher elements secured tothe base of said sleeve, and a churning vessel secured to said dasherelements so as to be rotatable with the sleeve, and adapted to hold themilk to be churned in contact with the dasher.

2. A churn attachment for a washing machine having a vertical dasherstandard which is partially rotatable back and forth about its verticalaxis, comprising a dasher element adapted to be mounted on and driven bysaid standard and comprising an annular bottom member with dasher bladesthereover, and a cylindrical marginal wall rising from the periphery ofsaid bottom and adapted to contain the milk to be churned.

3. As an article of manufacture, a churn comprising a receptacle havinga Cylindrical marginal wall, a removable cover, and a bottom; dashermeans secured to said receptacle, and a central sleeve rising axiallythrough the churn bottom and having means to couple it to an oscillatorychurn-operating standard.

4. A churn according to claim 3, in whichr 6. The combination, with atub of a washing machine, of a driven shaft projecting upwardly withinsaid tub, and a receptaole positively connected with said shaft so as tobe turnable therewith, the weight of said receptacle being borne by saidtub at the bot' tom thereof.

7. The combination recited in claim 6, together with a sleeve projectingfrom the inner surface of the tub and encasing the driven shaft.

8. The combination recited in claim 6, together with a sleeve projectingfrom the inner surface of the tub and encasing the driven shaft, andmeans connecting said sleeve with the receptacle, whereby displacementof the receptacle is prevented.

9. The combination with the tub of a washing machine, of a driven shaftprojecting upwardly within said tub, and a receptacle positivelyconnected with Said shaft. so as to be turnable therewith, the weight ofsaid receptacle being borne by said tub at the bottom thereof, and adasher element Within the receptacle.

In testimony whereof I aiix my signature.
